DCA++

  • Openness:3 ★★★
  • Document quality:2 ★★☆

DCA++ is a software framework to solve correlated electron problems with modern quantum cluster methods. This code provides a state of the art implementation of the dynamical cluster approximation (DCA) and its DCA+ extension. As the cluster solvers, DCA++ provides the continuous-time auxiliary field QMC (CT-AUX) , the continuous-time hybridization expansion (CT-HYB) restricted to single-site problems, the high temperature series expansion (HTS) and the exact diagonalization(ED).

Availability Building DCA++ requires a set of tools and libraries:
  • C++14 compiler (tested: clang >= 3.5, gcc >= 4.9)
  • CMake >= 3.3
  • HDF5 with the C++ interface (tested: 1.8.13 and 1.10)
  • FFTW3 or an FFT library with the FFTW3 interface (e.g. Intel MKL)
  • BLAS and LAPACK
  • MPI (if requested)
To enable the GPU support:
  • CUDA Toolkit (tested: 7.0, 7.5 and 8.0)
  • MAGMA (tested: 2.0.0 with CUDA 7.0 and 2.2.0 with CUDA 7.5 and 8.0)
